Product Description:
The LSM165-119-454-S-0KA is a brushless servo motor produced by Kollmorgen for the LSM Brushless Servo Motors series. This model delivers controlled rotary motion for automated packaging heads, gantry axes, and material-handling stations. It uses high-resolution sine-cosine feedback to relay precise rotor position, allowing the drive to modulate current and maintain commanded motion profiles with minimal error. The motor includes an M10 × 1.5 threaded shaft end that simplifies direct coupling to pulleys, gearheads, or load flanges. Its brushless design reduces wear because electronic commutation eliminates the physical contacts used in brushed motors.
The magnetic design provides a continuous output of 13.5 Nm while maintaining thermal equilibrium. This torque can be delivered up to the rated velocity of 4500 rpm, allowing the linear speed or cycle rate to remain consistent without overheating the motor. The stator is wound for a line-to-line voltage of 460 VAC, matching common three-phase power systems used in North American plants. A torque constant of 0.87 Nm/A links commanded phase current to developed shaft torque, allowing the controller to predict load response accurately. The winding has an inductance of 6.68 mH, which filters current ripple and influences current-loop bandwidth. These electrical characteristics support accurate current regulation during changes in motor speed and mechanical load.
For short bursts, the motor can reach a peak torque of 51 Nm, accommodating rapid acceleration or process disturbances before returning to normal operation. Achieving that output requires a peak current of up to 70.7 A, so the selected drive and cabling must safely support the resulting electrical and thermal loads. Dynamic behavior is also affected by a rotor inertia of 0.00092 kg-m²; this relatively low moment allows the axis to reverse direction quickly while damping minor load disturbances. Mechanical power is transferred through a shaft with a diameter of 28 mm. The thread extends 22 mm into the shaft end, providing sufficient engagement for securely clamping compatible couplings without additional adapters. The shaft arrangement is suitable for direct connections where accurate alignment and dependable torque transfer are required during repetitive motion.
